Addition resources

Students use number properties to solve problems without calculating.

Student solve addition problems where the missing value is located in different positions. This may mean that students transform the problem into a subtraction one. Students reflect on the easiest and hardest problems, and explain their choice.

Students show how they perform an addition and a subtraction problem, and write their own subtraction story problem.

Students explain why a range of students' answers to a maths problem are incorrect.

This task requires students to estimate some addition problems using any appropriate method.

This task requires students to estimate some addition problems using any appropriate method.

Students to show how they estimate in some addition problems.

Students estimate an addition problem, share their methods, discuss the averaging method, and then do more problems using averaging.

Students estimate an addition problem, share their methods, discuss the front-end method and then do more problems using front-end.

Students estimate an addition problem, share their methods, discuss grouping nice numbers, and then do a problem using this method, then design a question showing how it uses the method.

This practical task involves students making estimates of sets of items and demonstrating their method(s) of estimation.

In this practical task, students are to estimate the cost of meals ordered from a menu. The teacher reads out the meals and students show the steps in their estimations.

This practical task involves students making best estimates of sets of items and clearly demonstrating their method(s) of estimation.
